Sleep disturbance is a symptom of many mental health disorders that may negatively affect cognition and mood. Trauma-related sleep disturbance is a core reaction of traumatic stress and PTSD, similar to symptoms experienced by individuals with insomnia or other sleep-wake disorders. Although the cause and symptom progression of trauma-related sleep disturbance may be very different, research and clinical practice assess and treat it with measures and interventions designed for general insomnia. Using a cognitive model of insomnia modified for trauma-related sleep disturbance, the current study assessed the relations between select trauma and sleep variables within the proposed constructs of: 1) …

One possible variable is that of underlying dimensions, latent factors that give rise to these manifestations of psychopathology. This study explored potential underlying mechanisms of comorbid PTSD and depression, including negative affect, rumination, emotion dysregulation, neuroticism, and behavioral inhibition.

Thus, the …
